To all whom z't may concern:

Be it known that I, ELMER T. MAXWELL, a citizen of the United'States of America, and resident of lVheeling, county of Ohio, and State of West Virginia, have invented certain new and useful Improvements in Paper Dishes, of which the following is a specification.

This invention relates to paper receptacles of the rectangular type commonly employed by retail dealers in groceries and packing house products as containers for lard, butter and other soft, impressible and semi-fluid commodities; and it has for its object the provision of a rectangular nestable paper receptacle, commonly termed a paper dish, which, when its sides are pressed or collapsed into close approaching relation, retains its original form to the extent that its ends do not bulge or incline outward far enough to present their upper edges at a level below that of the edges of its sides.

As heretofore constructed, paper dishes of the type above referred to have had the upper edges of their ends disposed in or below the plane of the upper edges of their sides. The dishes so formed are objectionable as containers for some products, as butter and lard in a state of semi-fluidity, for the reason that the sides of the dish, when the latter is filled and grasped in the hand in the usual manner, naturally flex inward more or less into approaching relation under the applied pressure of the grasp required to support the weight; and such inward fiexure or partial collapse of the sides results in the ends of the dish being excessively bulged or inclined outward, lowering the upper edges of said ends below the level of those of the sides to the extent that the contents is liable to, and frequently does, overflow said ends, the tendency to production of such overflow being naturally increased by the displacement of the contents which results from the aforesaid reduction in the width of the intermediate portion of the dish.

As hereinbefore indicated, it is the aim of the present invention to provide a paper dish in which the objectionable feature of prior dish structures, above noted, is eliminated; or, otherwise expressed, to provide a dish of which the sides may be pressed or partially collapsed inward in opposite directions without inducing a resultant undue lowering of the ends.

In describing the invention in detail, reference is herein had to the accompanying drawings, in wh1ch- Figure l is a side elevation of a paper dish constructed in accordance with my inven tion;

Figure 2 is an end elevation of the same;

Figure 3 is a perspective view illustrating the dish supported in the hand in the usual manner, with the sides pressed inward towards each other; and

Figure 4 is agplan view, drawn to a reduced scale, of the blank of which the dish is for'med.-

Referring to said drawings, 1 indicates the sides, 2 the ends, and 3 the rectangular bot tom of the dish, said sides and ends being upwardly and outwardly inclined, rendering the dish readily nestable with other dishes of like form. Said dish is formed of a single blank of the approximate shape shown in Fig. 4:, said blank having its opposite side edges at parallel and shorterthan its axial length and having its end edges 5 parallel and shorter than its greatest width. Diagonally inclined edges 6 connect the side edges 4 tothe end edges 5 at each of the four corner portionsof the blank. Thus, as is apparent, the blank has the form of a rectangle with the corners thereof cut away on diagonal lines.

In forming the dish, the blank is folded on the various dotted lines shown in Fig. 4, the same being preferably scored preliminarily along said dotted lines to insure proper folding. Asshown, side lines 7 and end lines 8 define the bottom 3, said end lines being spaced from the adjacent edges 5 a greater distance than obtains between the sides lines 7 and the edges 4-. Each of the various pairs of lines 9 and 10 diverging outward in opposite directions from the corners of the bottom and meeting the adjacent end edge 5 defines a triangular gusset designed to ove lie the outer face of an internal member 11 located between the lines 10. Lines 12 forming obtuse angles with the side lines 7 of the bottom 3 extend from the various corners of said bottom to the adjacent side edges sniced distance from the an des 14 formed at the junction of the end edges with the adjacent inclined edges 6.

When the blank above described is folded into dish form, the inclined edges 6 have a substantially horizontal disposition and lie in the same plane with that portion of the adjacent end edge 5 which is located between the fold lines 10, as is best shown in Fig. 2, said edges together constituting the upper edge of the end of the dish; and, due to the disposal of the fold lines 9 and 10 in meeting relation to the edges and 5, respectively,'as spaced distances from the angles 13 and 11 said upper edge of the end of. the dish has substantially greater elevation than the sides of the dish.

The form of the blank employed in the formation of the dish, as aforesaid, is substantially identical with that which has heretofore been used in the formation of dishes. However, in shaping prior dishes the fold lines 9 have been in direct alinenient with, or coutinuations of, the side lines 7 of the bottom the fold lines 10 have had a greater inclination toward the longitudinal axis of the blank, the fold lines 12 have met the side edges 4 at the angles 13, and the'lines 8 have been spaced from the edges 5 a distance corresponding to that between the lines '7 and the edges 4L. The prior dish structures have consequently possessed ends whose upper edges naturally occupy a level slightly lower than those of their sides, thus rendering such dishes objectionable in the respect hereinbefore pointed out.

Another advantage possessed by the present invention flows from the arrangementof the fold lines 9 in meeting relation to the end edges 5 at points less remote from the adjacent angles 1%. Such arrangement, as is obvious, allows the two angles 14 of each end 2 of the formed dish to assume meeting relation much closer to the upper edge of such end than has been possible in prior structures, thus permitting the form-retaining wire staple 15 to be applied near to said edge, resulting in greatly increased rigidity and stability being possessed by such end over one in which the staple islocated approximately midway between the top and bottom edges thereof.

What is claimed isl. A paper dish formed of a blank having the form of a rectangle with its corners cut away on relatively short diagonal lines, the sides and ends of the blank being turned upward on lines defining a rectangular bot tom, each of said ends being formed by the production of two external end folds, a centrally disposed internal member and inter mediate gussets, said folds having their confronting edges inclined and extending into approximate meeting relation adjacent to the upper edges of said ends, said gussets being defined by fold lines which, in the blank, diverge in opposite directions from t l e cnds of the bottom-defining side lines, the relationship between the fold lines and the dimensions of the end folds being such that the blank when folded into dish form produces a dish having ends higher than its sides which relationship between the ends and sides is preserved when the sides are moved to a vertical position.

2. A paper dish formed of a blank having the form of a substantial rectangle with its corners cut away on relatively short lines, the sides and ends of the blank being turned upward on lines defining a substantially rectangular bottom, each of said ends being formed by the production of two external end folds, a centrally disposed internal member and intermediate gussets, said folds having their confronting edges inclined and extending into approximate meeting relation adjacent to the upper edges of said ends, said gussets being defined by fold lines which in the blank, diverge in opposite directions from the ends of the bottom-defining side lines, the relationship between the fold lines and the dimensions of the end folds being such that the blank when folded into dish form produces a dish having ends higher than its sides which relationship between the ends and sides is preserved when the sides are moved to a vertical position.

In testimony whereof, I aflix my signature in presence of two subscribing witnesses.
